Narrative:

I was working 2 combined positions final vector and arrival fix as well as a satellite airport (frg). It was beginning to get complex and I was moderately to heavily busy. There were 2 aircraft on converging courses 1 at 4000 nebound an light transport X and a widebody transport Y nwbound descending to 4000 ft. I became distraction because the sequencer was coordinating a runway change with me and another controller was pointing out an aircraft to me. When I looked back at the scope I noticed that the 2 aircraft were on conflicting courses about 5 mi apart. I descended the light transport X to 2000 ft and called traffic to both aircraft. The light transport X descended quickly and the widebody transport Y pilot reported him in sight and I instructed him to maintain visual separation. Had I not looked up at the scope when I did, it would have been too late to correct the situation. The moral of the story is that you shouldn't take your eyes off the radar scope when you are as busy as I was and I should have asked for the positions to be decombined when I realized that I was getting too busy.

Title: APCH CTLR WORKING MODERATE TO HVY TFC ALMOST HAD A LTSS OCCURRENCE DUE TO LACK OF VIGILANCE.

Narrative: I WAS WORKING 2 COMBINED POSITIONS FINAL VECTOR AND ARR FIX AS WELL AS A SATELLITE ARPT (FRG). IT WAS BEGINNING TO GET COMPLEX AND I WAS MODERATELY TO HEAVILY BUSY. THERE WERE 2 ACFT ON CONVERGING COURSES 1 AT 4000 NEBOUND AN LTT X AND A WDB Y NWBOUND DSNDING TO 4000 FT. I BECAME DISTR BECAUSE THE SEQUENCER WAS COORDINATING A RWY CHANGE WITH ME AND ANOTHER CTLR WAS POINTING OUT AN ACFT TO ME. WHEN I LOOKED BACK AT THE SCOPE I NOTICED THAT THE 2 ACFT WERE ON CONFLICTING COURSES ABOUT 5 MI APART. I DSNDED THE LTT X TO 2000 FT AND CALLED TFC TO BOTH ACFT. THE LTT X DSNDED QUICKLY AND THE WDB Y PLT RPTED HIM IN SIGHT AND I INSTRUCTED HIM TO MAINTAIN VISUAL SEPARATION. HAD I NOT LOOKED UP AT THE SCOPE WHEN I DID, IT WOULD HAVE BEEN TOO LATE TO CORRECT THE SITUATION. THE MORAL OF THE STORY IS THAT YOU SHOULDN'T TAKE YOUR EYES OFF THE RADAR SCOPE WHEN YOU ARE AS BUSY AS I WAS AND I SHOULD HAVE ASKED FOR THE POSITIONS TO BE DECOMBINED WHEN I REALIZED THAT I WAS GETTING TOO BUSY.
